Design outcomes

Primary

Measure	Time frame
Experiment 1: The main parameter in Experiment 1 is a measure of sensitivity to audiovisual synchrony, the JND. The JND in experiment 1 reflects the smallest time difference (in milliseconds) between sound and vision that participants are able to detect. Experiment 2: The main parameter in Experiment 2 is the JND for visual temporal order. Here, the JND reflects the smallest time difference (in milliseconds) between two flashes that participants need to perceive correct visual temporal order.	—
